Flow cytometric analysis of lung cells.

Flow cytometry results for each cohort of L-MSCS show high similarity for surface antigens CD44 and CD81. L-MSCs were negative for immune cell marker CD11b, and hematopoietic markers CD79a, CD117 and HLA-DR. Values are presented as the mean + SEM for surface antigen marker. n = 4–6 for each group.各队列的L-MSCs流式细胞术（Flow Cytometry）检测结果显示，其表面抗原CD44与CD81的表达水平高度相似。L-MSCs对免疫细胞标志物CD11b、造血标志物CD79a、CD117及人类白细胞抗原DR（HLA-DR）均呈阴性表达。表面抗原标志物的检测结果以平均值±标准误（SEM）表示，每组样本量n=4~6。
